Purpose: To find and pair six different muscles in the chicken wing, in order to observe and understand the details of how muscles are involved in movement.
1. First, I put on my surgical gloves.
2. Then, I gathered all of the materials needed for this lab. 3. Before dissecting, I noted how the chicken wing appeared. I recorded these characteristics. 4. I then began the dissection by skinning the chicken wing. This allowed me to observe the fascia. 5. After skinning the chicken to the point where I could see the epimysium, I began using the forceps to pull on the individual muscles. 6. Once I found the different muscles that cause movement, I took notes and drew diagrams of the muscles. I then labeled which muscle was contracting and which was relaxing. I also labeled which muscle was the flexor and which was the extensor. 7. After finishing all of the directions given, I then disposed of my chicken wing in the designated trash can. 8. Then, I washed my dissection pan, forceps, and lab station. 9. Finally, after everything was completed, I washed my hands with soap and water.
